As far as putting sessions in a database, boy oh boy, I don't like that idea much at all. Calling out to a database
There is not to much you can do without calling out to a database these days anyways, Java, PHP, Perl ect. all pretty much are all good at connecting to databases to the point we don't even think of it as unusal anymore. My guess is that having your servers properly configured and tuned, is going to make a bigger difference than language, database connection, or any other single factor.
Well we know that some GPL'ed code is in OpenServer due to samba being in there; kinda makes you wonder what would be found if some neutral third party went through the code with the same microscope that they are using on Linux.
Might be interesting to go through OpenServer looking for copyright notices and find out how much is supposedly from SCO and how much is admited to be from third parties.
I have a COSMAC elf! that I built circa 1975, the "motherboard" is perfboard with sockets that are hand wirewraped together. the processor is a RCA 1802 that runs at 1.8 Mhz and is connected to 255 bits of static ram.
the machine is programmed by setting the load/run switch to load, flipping the byte togle swithes to the bytes bit pattern and pushing the single-step button to put the byte into memory.
I never got the thing to actualy run but its pretty cool for it's "OMG" factor
SCO could win the case but still fall prey to IBM's patent violation claims. personaly I think this is why SCO is trying so desperatly not to show exactly what code they claim is in violation. If SCO was required to remove all code that violated an IBM patent, there might not be anything left.
The crux of the matter is SCO can revoke for cause, when the licensee is in violation of the contract.
One point that may cause a violation is the release of code that is a derivative, of code that was placed in SVR4, such as IBM made a journalizing files system for SVR4 unix such as AIX, released the code as in distributing AIX then took that code out and made minor mods and released it in LINUX. That in my second and third hand lay knowlege of the issues would violate the contract and alow SCO to terminate IBM's SVR4 liciense. IBM will of course argue that the file system was developed indepently of the operating system and that a derivative of the file system was later modified and place in AIX, and that the filesystem that went into LINUX was again taken from the independant, pre-SVR4 sources and therefore not a unix derivative covered by the licience and contract terms.
If the court buys SCO's version, IBM's goose is cooked, they lose their SVR4 liciense and owe SCO $3 billion; If the court buys IBM's version, SCO's goose is cooked and their assets go on auction, and their officers probably get hefty fines from the SEC and or jail time.
SCO even if they win, lose because they've pissed away good will they might have had in the developer community, and what good is an operating system with software that was state-of-the-art circa 1980, for businesses in the 2003?
The other "surprise, surprise" is that EXT2 is still very good for many uses. especialy if the file system can be mounted read-only; you could do this in partitions like/boot,/opt,/lib, and/usr that hold programs and are not changed often.
I wonder if the kernal version makes a difference, are the xfs and jfs better on the 2.6 as compared to say the 2.4.19 that I'm running now; or how about with files that are much smaller like on the typical web server?
also partioning schemes can make a big difference in overall performance, in the old days i placed the swap partition in the center of the disk (most accessed in the center where the heads are most likely to be) the next most likely like/usr and/var beside the swap so the heads didn't have to move to far to get to them ect.
also does the disk make a difference, such as is any performance differences consistant between scsi and ide drives?
These are things that need to be looked at before make a decision as to which is best, but it definately appears that we need to do some looking now
Actualy a lot of organisations prefer a fuedal system where a samll group is given authority over the masses and can work their whims in a closed and opaque manner; big bussiness and dictatorships are good examples.
I suspect this will be especially true in poor countries
These poor countries, are these the same countries where people actualy believe that Microsoft's Windows XP costs $5.00 and $199.00 is twice the meadian anual per capita income?
its a sheet that looks kinda like an IRS form 1040 or 1040a which everbody in the US that doesn't live in Nevada or Alaska fills out every year. (Alaska actualy makes a profit on oil revenues, so they pay pay their residents instead of taxing them!) .
doesn't apply, because the tax is exactly the same for a in state sale as for an out-of-state purchase, for use in your home state. the short version, you are taxed for what you use, not where you bought it.
the court said that a third party, the retailer couldn't be expected to be able to collect taxes for 3700 different jurisdictions, from the purchaser, unless the retailer had a physical presence in that jurisdiction and therefore the expertice to collect the tax in that juricdiction. If I have a store in NYC then I know how to collect the taxes for NYC. the county and the state of NY. The unified law takes away the multiple jurisdiction argument.
What happened to interference with interstate commerce?
actualy your are supposed to pay the sales/uses taxes for your purchases, the retailer is just pressed into service to collect them, your state could just as easily have the retailer report sales to them and the state could just compare lists and hit you for interess and penalties on what you didn't cliam on your taxes.
sorry dude I hate to be the one to break the bad news to you but just because a retailer wasn't preeded into service to collect taxes on your purchases, doen't mean that you don't owe them your self
actualy it's not a new tax, most states have a sales/use tax and if you buy something where the sales/use tax isn't collected for you by the bussiness, your supposed to pay them yourself, usualy on your state income tax form. Nobody of course does it unless they have to be squeaky clean, or its a very well advertised purchase. I think the i remember that the CEO of Tyco got in trouble for not paying the sales/use taxes on a painting he bought from $20M or something like that.
what is new is that a bussiness couldn't be forced to collect the sales/use taxes for a state that they had no physical presence in such as if I had a Michigan sales tax license, California couldn't force me to collect tax for shipments to california.
Actualy find a bird is easy, I've done it several times, the trouble is that while we are fairly astute about such things, many are not. would you realy want 6-pack joe pointing a satelite transmitter at what he thinks is the right spot, and knocking an entire country's big football game off the air?
aren't able to separate between technobabble and someone that really has a clue.
ME:Do you block out-bound port 25? AOL Tech: Sir We do block any ports ME: then why can't I send Email to my server through AOL? AOL: We have no open issues with Email today, other users are sending mail just find, are you sure your email client is set up properly? ME: I can send Email to MY server just fine through an other ISP, but I can't through AOL, do you block out-bound SMTP port 25? AOL: Sir did you say My server? ME: yes I can connect to POP3 service, port 101, on poiuyt.com just find through AOL; but I cannot connect to SMPT service on port 25 at poiuyt.com through AOL but can through other ISP's; do you block out-bound port 25? AOL: Sir are you using AOL's email server? ME: no I am not, if I was using your email server then all of the email that I send for poiuyt.com, would be stamped as coming from AOL.com not poiuyt.com and people might think they were spam because the email's from and recieved lines would not match. AOL; Sir AOL has very srtict policies against sending SPAM ME: I understand this and I agree, is one of those policies, blocking the sending of Email to outside servers? AOL: Why yes it is, we do not alow AOL users to send email to ouside email servers as one of our spam prevention policies ME: Then why didn't you just say, yes we block out-bound port 25 to prevent spam 10 minutes ago?
I aways though a hacker was someone who made things (hardware or software) without engineering expertise and took great delight in finding unimplimented features, unusual uses, new and unanticipated uses, and of course ringing out every bit of performance possible.
I for one would hesitate to drop an knowlingly-insecure machine out there
as would most of us at/. unfortunately, the average non-/. computer user realy doesn't understand how easily an un-maitained machine realy is to crack or why someone would want to. These cracker/spammers are a rare breed to them and they think that they are relatively secure, both through the software on the machine, after all microsoft is a big company employing lots good programmers so their product must be secure enough for typical use, and secondly they feel that they are such a little fish in the big internet pond that none of the evil crackers will notice them.
patches are of course just a big pain, and a lot just skip them, ever try to download a 1.5 Mb patch thru a dialup modem connected at 28K? And of course if your OS is bootlegged, you wouldn't dare go to microsoft for the patches anyways.
I remember reading about some guys at MIT that made a linux CD specificaly made to find all of the drives on a machine and does a cryptographic shreading on them; just enable boot from cd in bios, popin the cd and boot the machine and it automaticaly shreds the disks by writing a pattern of zeros and other numbers to change every bit to an zero, military grade zero!
No it seems to be plain old piss poor proceedures to me, it's not that hard to fix either. The machine is physical so someone has to physicaly remove it from the bank branch/dept;
1 so that person unplugs the ethernet, pops in a linux cd, turns on the computer, boots into linus and shreds all of the harddrives on the machine.
2 turns off the machine, and signs a line on the frome that the machine has been shredded; and wittnessed by the branch/dept manager. Places a sticker on the machine that states it is shredded; with both signatures.
3 removes the machine physicaly, has the branch manager sign that the machine is physical removed on the form, and the branch/dept manager has the removal tech sign for the property removed.
4 on recieving the completed form, accounting moves the property from the inventory of capital assets to the salvage account.
then its sent to salvage where they again shred it like they didn't do in the story and recycle. Not real hard to do and it fitts into normal business methods without any real changes.
the way I understand it what each perish can and cannot do is controled localy by the church Bishop and elders; and yes some Amish perishes have been allowed auto ownership. Each perish also tends to have a few members that push the limits a bit; this alows the perish to see how things tend to be heading and consider alowing or disalowing new things.
The Amish definately dislike hardline phones in the home because the incessent ringing interuptes family life; most Amish with hardline phones keep them in an outhouse! Cell phones are popular with the Amish, a solar charge alows the phone to be charged with out the house being tied to the outside.
Amish tend to disalow things that 1.interfere with family or social interactions 2. tye them to the outside world or make them depend on others especialy if the others are outside the Amish community.
Alsosremember that the Amish embraced a particulary revolutionary technology call crop rotation, this alowed one farmer to grow enough crops to sustain many people which allowed the industrial revolution to occure.
McBride did say that solaris is safe, which implies that everything else may not safe. If SCO manages to claim BSD as a SVR4 derivative, and therefore their "IP", then of course all of the windows 9X OSes would need their unix, binary runtime liciense, as they all had BSD code in them, not sure about the Win NT series. With both Windows and Mac OS X needing their liciense, SCO could overtake Microsoft as the big dog on the desktop.
they have allways concentrated on the case on copyright infringment Copyright infringement? I don't remember anything about copyright infringement unless your talking about the continued distribution of linux by SCO in violation of the GPL. I'll grant that there definetly is code in both IBM AIX, Sequent's Dynix, and Linux that is common but is that because its IBM's code to do with as they please because they own it, is it because it code that IBM got in SVR4 and distributed illegaly, or is it because the code in question either came from BSD or is too trivial to appear different?
The case is not about copyright infringement, SCO is very carefull not to talk about copyright infringement, which has a legal definition, but rather talks about The undefined, nebulous concept of intellectual property. SCO may hold the licenses for both IBM and Sequent, and both those licienses are reported to have very different terms, and since IBM now owns Sequent and its IP, which liciense applies may either make or break SCO's arguements. Also it's interesting to note that IBM's OS390 is the only UNIX that has no lineage to the original AT&T unix.
A tuned pipe increases performance quite a bit, freq is about 60Hz/16 or 3.5Hz, don't need to get to fancy, it only has to hit one frequency so freq response can be about nil, a small speaker sent a spike every 3.5Hz will resonate.
